Greek-born Salpa, 26, entered the Big Brother house last night where she will live alongside shamed reality star Frankie Cocozza, who is back on TV two months after being kicked off the X Factor.
The would-be pop star is joined on the Channel 5 show by former Welsh rugby captain Gareth Thomas, who surprised the sporting world in 2009 when he came out as gay.
Thomas, one of his country’s most capped players, is working on a film about his life starring American actor Mickey Rourke.
They are joined in the house by Loose Women star Denise Welch, former EastEnder Natalie Cassidy and actor Michael Madsen.
Also appearing are Kirk Norcross from The Only Way Is Essex, and footballer Ryan Giggs’s sister-in-law, Natasha.
Salpa’s agency boss Andrea Roche said: “I’d say she’ll do very well. She has a great personality and is really different from what you would expect. People in Ireland will get to see the real Georgia in there. She’s actually very down-to-earth and very easy going, she’s not what you would expect a model to be like.”
Salpa’s modelling career started when she was 14. She has promoted everything from fake tan to wrestling.
She also reached the final of FHM magazine’s search for a High Street Honey while a relationship with Calum Best kept her in the news.
Cocozza, who left the X Factor after boasting about drug taking, said he hoped to make a career for himself in TV. He said: “I’d like to be like George Lamb, he’s cool.”
The other contestants in the show are singer Andrew Stone, Playboy models and twins Kristina and Karissa Shannon, former So Solid Crew star Romeo Dunn and page 3 girl Nicola McLean.
Former Big Brother winner Brian Dowling is presenting the show.
